Copper(I) iodide can be prepared by heating iodine and copper in concentrated hydroiodic acid. [9] In the laboratory however, copper(I) iodide is prepared by simply mixing an aqueous solution of potassium iodide and a soluble copper(II) salt such as copper(II) sulfate. [4] 2 Cu 2+ + 4 I − → 2 CuI + I 2
Copper is a chemical element with the symbol Cu (from Latin: cuprum) and the atomic number of 29. It is easily recognisable, due to its distinct red-orange color.Copper also has a range of different organic and inorganic salts, having varying oxidation states ranging from (0,I) to (III).
The tables below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure.
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
Additives: Nearly 70% of table salt in the United States is fortified with iodide, a necessary nutrient that's been added to salt since the 1920s to help prevent iodine deficiency, according to ...
Copper compounds, whether organic complexes or organometallics, ... Attempts to prepare copper(II) iodide yield only copper(I) iodide and iodine. [1]
These may be metal salts containing iodide ion such as ... Copper(I) iodide; Curium(III) iodide ... iodide; Erbium(III) iodide; Eschenmoser's salt; Ethylenediamine ...
In chemistry, a salt or ionic compound is a chemical compound consisting of an assembly of positively charged ions and negatively charged ions , [1] which results in a compound with no net electric charge (electrically neutral).
